This invention relates to a fuel burning logset and a freestanding hearth and more particularly to a set of artificial non-burning logs and a fuel burner mounted on a hearth or in a fixed fireplace for producing flame, to provide, in combination with the logs, an aesthetic impression of a naturally burning wood fire.
It is desirable to provide an aesthetic impression of a naturally burning wood fire but without actually burning natural wood products, both in existing fireplaces and in freestanding or non-fireplace environments, as well as out-of-doors. Additionally, while artificial logsets used in conjunction with natural gas or other sources have been proposed, it is desirable to produce an aesthetic appearance of a naturally burning wood fire in a freestanding hearth-like fire setting. Most, if not all, of the prior artificial logsets are typically utilized in an existing fireplace in conjunction with a chimney flue or the like, or in a freestanding circular or square geometric configuration providing a luminaria effect. It is desirable to produce a hearth-like setting for an open fire which is not limited to use in a present standing fireplace and does not constitute a fully enclosed fire burning compartment, such as those sold as luminaria or the like.
To these ends, according to one aspect of the invention, an artificial logset is provided for producing the aesthetic appearance of a wood burning fire. The logset includes a base, a flame deflector pivotally mounted on the base and a fuel burning chamber removably mounted on the base. The logset further includes at least a pair of artificial non-burning log members, with one of the log members being removably mounted on the base and the other being removably mounted on the flame deflector. A linkage connects the flame deflector to the base for movement relative to the base, with the linkage being operably effective for supporting the flame deflector and the log member mounted thereto above the chamber when a fire is burning in the chamber and, when lowered, the flame deflector is proximate the chamber it is operably effective for extinguishing flame burning the chamber.
The artificial logset can further include a spring that biases the flame deflector toward an upward direction away from the burning fuel chamber. The spring can be sized and configured so that a space exists between outwardly extending lips at the upper end of each side of the fuel burning chamber and the flame deflector. This permits flames to escape the chamber out of the top, through the spaces and adjacent at least one of the non-burning log members when a fire is burning in the chamber for producing an aesthetic appearance of a wood burning fire.
The logset can also include an operating handle attached to the flame deflector for raising the flame deflector away from the chamber for loading fuel into the chamber and for lowering the flame deflector toward the fuel burning chamber to position the logset in an operating condition. When desirable, the handle can be used to lower the flame deflector further for extinguishing a burning flame in the chamber.
The non-burning log members can be removably mounted to the base of the flame deflector via a plurality of clips, thereby permitting easy installation and removal of the non-burning log members.
According to a second aspect of the present invention, a freestanding fireplace hearth is provided that includes a cradle and a leg assembly supporting the cradle. The hearth further includes a rear curved deflector extending upwardly from a rear edge of the cradle, with the deflector being mounted to at least one of the cradle and the leg assembly. The deflector further includes an upper, freestanding edge disposed upwardly and forwardly from the rear edge of the cradle.
The leg assembly can include at least one mount adaptor integral with a rear portion of the leg assembly. The rear curved deflector can include a lower flange portion that extends downwardly away from a remaining portion of the deflector having an arcuate shape as viewed in side profile, with the lower flange portion of the deflector engaging the at least one mount adaptor of the leg assembly, thereby mounting the deflector to the leg assembly.
The cradle can include a rear downwardly extending flange that also engages the at least one mount adaptor of the leg assembly and the downwardly extending flange of the cradle can be disposed between the leg assembly and the lower flange portion of the deflector. The cradle can further include an arcuately shaped portion attached to a forward portion of the leg assembly.
The at least one mount adaptor of the leg assembly can comprise a plurality of upwardly facing hooks integral with a rear portion of the leg assembly. In this case, the lower flange portion of the deflector can have a plurality of recesses formed in the lower edge thereof, with each of the recesses engaging one of the hooks thereby mounting the deflector to the leg assembly.
According to a third aspect of the present invention, an apparatus is provided comprising a freestanding fireplace hearth having a cradle and a leg assembly supporting the cradle, and a rear curved deflector extending upwardly from a rear edge of the cradle. The apparatus further includes an artificial logset having a base disposed on the cradle with the logset further including a flame deflector pivotally mounted on the base and a fuel burning chamber removably mounted on the base. The logset also includes at least a pair of artificial non-burning log members, with one of the log members being removably mounted on the base and the other of the log members being removably mounted on the flame deflector.
The freestanding fireplace hearth and the artificial logset can include various combinations of the features discussed previously with respect to the logset and the hearth.
This invention will be more readily apparent from the figures, which are described as follows:
Referring now to the drawings,
The artificial logset 10 of the present invention further includes a base 22 with the fuel burning chamber 16 being removably mounted on the base 22 and positioned on base 22 by a plurality of studs 24 extending upwardly from the base 22. Accordingly, the fuel burning chamber can be easily removed from the base for cleaning or emptying. The fuel burning chamber 16 can also be positioned on base 22 by a variety of other means as may be appreciated by one skilled in the art.
The artificial logset 10 also includes a flame deflector 26 that converges downwardly as best shown in
The flame deflector 26 is pivotally mounted on base 22 in the illustrative embodiment by a linkage including first set 28 of parallelogram linkages having links 28a and 28b and a second set 30 of parallelogram linkages (one link shown). More particularly, in the illustrative embodiment, the flame deflector 26 is pivotally mounted to a rear portion of the base 22 as may be appreciated by reference to
The lower links of the first set 28 and second set 30 of parallelogram linkages are coupled to one another by a common hinge pin 38 which is rotatably coupled at one end to the rear flange 32 of base 22 and is rotatably coupled at the other end to a similar structure (not shown) of base 22. The lower links of the first set 28 and second set 30 of parallelogram linkage are fixed to pin 38 by conventional means so that the lower links of both sets 28 and 30 of parallelogram linkages pivot about a longitudinal centerline 40 of pin 38. A handle 36 is integral with the first set 28 of parallelogram linkages and is operably effective for moving the flame deflector 26 relative to the base 22 in various positions such as those illustrated in

As shown in
It will be appreciated that the log members 12, 14 are essentially non-burning artificial members configured of any suitable materials and coloration to produce the aesthetic appearance of a burning log. Such logs can be made of fiber/ceramic or any other suitable flame resistant materials. Log member 12 is made as a monolithic construction but includes various slots and openings such as slots 56, used for mounting, and an aperture 13 (
The fuel burning chamber 16 includes a bottom wall 58, a forward wall 60a and an opposing rear wall 60b extending upwardly from the bottom wall 58. The forward wall 60a includes an outwardly extending lip 62a at an upper end thereof. Similarly, the rear wall 60b includes an outwardly extending lip 62b at an upper end thereof. In operation, after the gel-like fuel 18 is added to the fuel burning chamber 16, as depicted in
When it is desired to extinguish the burning fire, the handle 36 can be grasped and pulled downwardly, thereby further lowering the flame deflector 26 against the bias of the spring 44 so that the deflector 26 comes into such close proximity to the lips 62a and 62b, or contact with lips 62a and 62b, of the fuel burning chamber 16 so that any burning flame is extinguished. The flame extinguishing position of the artificial logset 10 is illustrated in
The freestanding fireplace hearth includes a cradle 72 and a leg assembly 74 that supports the cradle 72. The hearth 70 further includes a rear curved deflector 76 extending upwardly from a rear edge 78 (best seen in
In the illustrative embodiment, the leg assembly 74 includes a pair of spaced apart forward legs 84 interconnected by a cross member 86. The leg assembly 74 can further include a pair of spaced apart rear legs 88 interconnected by a cross member 90. For further stability the leg assembly 74 can include a pair of struts 92 disposed on either side of the leg assembly 74 and interconnecting corresponding ones of the forward 84 and rear 88 legs. In the illustrative embodiment, the rear cross member 90 includes a pair of flanges 94, disposed at a top end thereof, with each of the flanges 94 being disposed at contacting engagement with one of the rear legs 88. Similarly, the cross member 86 includes a pair of rearwardly extending flanges 96 (one shown), with each being disposed in contacting engagement with one of the forward legs 84. The cross members 86 and 90 can be secured to the forward 84 and rear 88 legs, respectively, as subsequently discussed.
As best seen in
The assembly of the freestanding fireplace hearth 70 can be further appreciated with reference to
The curved deflector is lowered until the recesses 104 of the flange 102 engage hooks 106 of the leg assembly 94, thereby mounting the deflector 76 on the leg assembly 74. In the illustrative embodiment, the flange 100 of the cradle is disposed between the leg assembly 74 and flange 102 of deflector 76, giving the appearance of a joint or seam 112 between cradle 72 and deflector 76. As may be appreciated by one skilled in the art, mount adaptors other than the hooks 106 can be used for mounting the cradle 72 and curved deflector 76 to the leg assembly 74. Furthermore, the cradle 72, leg assembly 74 and curved deflector 76 may be mounted to one another in other ways within the scope of the present invention. For instance, rivets 110 may be omitted, with the arcuate portion 98 of cradle 72 resting on top of the leg assembly 72. In this embodiment, the cross members 90 and 96 may be attached, by tack welding for instance, to the rear 88 and forward 84 legs, respectively. As another alternative, holes may be included in flange 100 of cradle 72, the lower flange portion 102 of deflector 76 and cross member 90, with flange 100 and lower flange portion 102 attached to cross member 90 using conventional fasteners. In yet another alternative embodiment, the arcuate portion 98 of cradle 72 may be made as a one piece construction with the lower flange portion 102 of deflector 76 being omitted, as well as the flange 100 of cradle 72. This one piece deflector and cradle can be secured to the leg assembly 74 using various conventional means including fasteners, and others.
As best seen in
The shape of the curved deflector 76 and the spatial relationship between the deflector 76 and the fuel burning chamber 16 can be selected to minimize flame damage, such as tarnishing, to the forward surface of deflector 76. In one embodiment, this can be accomplished as follows. The fuel chamber 16 has a width D1 shown in
In operation, the freestanding fireplace hearth compliments the aesthetic effect of the artificial logset, when a fire is burning in the fuel burning chamber 16 of logset 10.
Further advantages and modifications will be readily apparent to those of ordinary skill in the art without departing from the scope of the invention and applicant intends to be bound only by the claims appended hereto.
